The answer is -7 because :
a=1, b=1, c=2
Discriminant = b^2 - 4ac
= 1^2 - 4*1*2
= -7
Answer:
n=7
Step-by-step explanation:
I feel like you need the answer now so i'm not gonna write one.
Answer:
amt. the shop spends on 40 pairs
= $11 × 40
= $440
amt. paid extra (due to fixed cost) per pair
= ($450 - $440) ÷ 40
= $0.25
amt. per pair to break even
= $11 + $0.25
= $11.25
Isolate x.
24x = 48 - 2y
Divide by 24.
x = 2 - y/12

As we know that cotx= 1/tanx
cot36° = 1/tan36°
=>cot36°= 1/0.726543
=>so cot 36°= 1.376382
So correct answer is option D.
